  . .

2. What kind of 
angles are 1 
and 5?

3. What kind 
of angles 
are 6 and 
8?

4. Set it up and solve. They are alt int angles

5. What kind of 
angles are 7 and 3

6. Yes. The corresponding angles are congruent

7. Draw an example of consecutive interior angles?

8. No

9. Write the equation of a line that is parallel AND perpendicular to y = 2x-7 and goes through (6,-4) Answer Parallel: y = 2x -16 Perpendicular: y = -1/2x -1

12. Converse Inverse Contrapositive If I am buff then I am Mr. E

14. Write the equation of a line that is parallel AND perpendicular to 5x-4y = 12 and goes through (20,-7) Solve for y. So you get y = 5/4x-3 Then do the same thing as the other problem

15. set it up and solve

16. What kind of 
angles are 3 
and 5?

18. Consecutive angle add up to 180

19. What kind of angles are 4 and 12

20. Which angles are linear pair with angle 6

24. Solve for X and Y 7y (8x+40) Answer. Extend the parallel lines and transversal. Notice the angles are consecutive interior angles which means 8x+40+6x=180 6x (3y-10)

25. Tell if the lines are parallel, perpendicular, or neither. Line 1: (-4,5) (7,1) Line 2: (-7, 3) (-9,-5) Use the slopes formula. If they have the same slopes they are parallel. If they are opposite reciprocals then they are perpendicular. If neither, then they are neither
